BANTA, OF OLEALRFIELD, PENNSYLVANIA BUILDING WALL Original application led Hay 11, 1927, Serial No. 190,606, now Patent No. 1,765,255, dated June 17, 1930. Divided and this application led May 26, 1930. Serial No. 455,727.

This invention relates to an improvement in building walls, and is a division of my former application Serial No. 190,606, filed May 11, 1927, now Patent No. 1,7 65,255,

granted June 17 1930.

The. object of the invention is to provide an improved insulating wall which may be used in buildings or wherever desired and of a construction such that it will be a good insulator for heat, cold, or sound, and is particularly adapted for refrigerators, refrigerator cars, etc., or wherever it is desired to provide an insulating wall or partition either for a building or an article o f manufacture.

rPhe invention relates to the formation of a Wall of a series of dead-air spaces which are made air-tight by means of liquid or plastic cement, covering the entire inner surfaces of the dead-air spaces. The wall is formed in a section by constructing a series of cells inclosing the sides thereof by means of a sheet or board, after which a predetermined quantity of plastic or li uid cement is poured into each of the cells an the are covered yover by an'- other sheet, upon W ich is built and likewise filled any number of additional cells to provide a wall of the desired thickness. It may be og one cell thickness or any number as desire V After the section is thus closed and formed withthe top board or sheet secured over the cells, the enti're section is mounted upon a shaft and rotated slowly in order to allow the cement to run into and fill all ofthe crevices or air openings, as well as over all of the internal surfaces of each cell, and in that way providing an air-tight dead-air space within each cell of the entire section, thus forming a section which provides a good insulator for heat,cold, or sound, and may be used in any suitable manner for building.

The coating on the inner surfaces of the dead-air spaces is preferably water-proof and air-proof, making the construction comparatively inexpensive and practical as well as forming an eiiicient and well insulated wall that is water-proof and air-proof.

In the accompanying drawings:

Fig. 1 is a side elevation of a section of portion of one of the cells.

The wall is .preferably formed or constructed as shown more particularly in Fig. o0

2, in which one side 1 of the wall is placed 1n a flat position and upon this is secured the framework 2, which may be formed of longitudinal and transverse members suitably crossed at intervals in order to reinforce the wall as well as to form cells 8. A suitable quantity of liquid or plastic cement is then poured into each of the cells 3 and another oard or sheet 4 is secured over the tops of the cells entirely closing them. This provides a wall of one air space or cell thickness and may be used if desired, although the wall may be of two or more cells thickness, the one shown in the drawings being of two cells thickness. In this form, another frame 5 is 75 secured upon the board or sheet 4 in order to form additional cells 6 therein, and these cells are likewise closed by a similar sheet or board 7, after they have received the desired or predetermined quantity of plastic cement. The sheet 7 forms one side of the wall while the sheet 1 forms the other.

As thus constructed, the section of the wall is then secured in suitable clamps 8 of any desired construction and mounted on a shaft or shafts 9, journaled in suitable bearings 10. The construction and mounting of the clamps 8, shafts 9 and bearings l0 may be of any desired form, and the one shown in Fig. 1 is merely for the purpose of illust-ration.

Any suitable means, as the pulley 11, may be used for rotating the shafts 9 with the section of wall carried thereby, and in this way the wall is slowly rotated allowing the plastic or liquid cement to run over all of the internal surfaces ofthe cells 3 and 6, filling the cracks and crevices and truly forming closed dead-air spaces or cells within the wall. Attention is called to Fig. 4 as showing the manner in which the plastic cement fills the cracks and covers the surfaces of the cells.

After removal from the clamps 8, the section of wall may be fitted into place Whereever it is desired to be used. The wall may be built of any desired size and shape, ac-

cording to its use, and it is not desired to limit the invention to the exact form shown.

The building Wall thus formed provides a waterproof and air-proof structureand is a good insulator for heat, cold or sound, this being accomplished by the closed, dead-air spaces of which the wall is formed. The Wall is particularly adaptable for refrigerators, refrigerator cars, and suitable structure, or wherever it is desired to provide an insulating Wall or partition for a building or an article of manufacture. The wall as thus formed is inexpensive and thoroughly practical. l

The cost of such a Wall would be about fifteen (15) cents per square foot as compared with sixty (60) cents per square foot, for the ordinary refrigerator Wall, and is more eflicient because it is a better insulator 'than is usually thus obtained in the ordinary refrigerator wall.

The Wall may be constructed of any suitable material desired, as for instance Wood or a composite material, or Whatever it may be found advantageous to use. The use of the word cement in the claims is intended to cover not only all forms of cements but-also glues and other plastic or liquid substances which may be used for coating the interior of the air spaces or cells to render these substantially air-tight.

1. A building Wall of the character described comprising sides forming one or more cells havin@` cement on the interior surfaces thereof, ma ing said cells substantially airtight.

2. A building Wall of the character described comprising sides forming one or more cells having the interior surface thereof substantially coated with cement for rendering said cells substantially air-tight. y

3. A building Wall of the character described comprising sides forming one or more cells having the inner surfaces thereof coated and rendered substantially air-tight by means of cement.

4. A wall of the character described having sides arranged to enclose a plurality of cells, each of said cells having a coating of plastic or liquid cement on the inner surfaces thereof entirely covering the inner surfaces and filling the cracks thereof, rendering the wall substantially air-tight.

5. An insulating Wall comprising sides arranged to enclose a cell, and a coating of cement covering approximately all of the interior sides of said cell to render the same approximately air-tight.

8. A heat insulating wall, comprising a plurality of cell forming and enclosing side*v Walls enclosing one or` more cells twithin the wall, and a coating of cement covering the inner Walls of the cells to render the same Vapproximately air-tight. i

In testimony whereof I affix my si ature.
